External mastic in Fairwarp
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you have damp patches traced to an open external joint and rigid filler in a joint that should flex, we can help, whatever the surface.
In a village or hamlet like Fairwarp, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Your job is guaranteed for a year, as with all our work.

External mastic in Fairwarp: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St John the Evangelist Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Questions from Fairwarp
Do you work for landlords with property near Buxted station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Fairwarp in your area for external mastic?
Yes, Fairwarp is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear price.
How long does external mastic take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll say how long yours will take.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
How do I get a quote for external mastic in Fairwarp?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
What we’re called out for in Fairwarp
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
- Hard, crazed mastic that has stopped moving
Rented homes near Buxted station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- When the joint can take water or movement
- Whether all the old sealant comes out first
- What preparation is included
- How much experience the applicator has
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that’s more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Brickwork movement joints
- Façade panels
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.

- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit

- For indoor joints, keep the area dry beforehand if you can

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
- Fix overflowing gutters above sealed joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
